The Preventative Coup of November 11,[1] sometimes called the 1955 Brazilian coup d'état or referred to as an "anti-coup"[2] or a "counter-coup"[3] (Portuguese: Novembrada, Movimento de 11 de Novembro, Contragolpe, Golpe Preventivo do Marechal Lott), was a series of military and political events led by Henrique Teixeira Lott[4] that resulted in Nereu Ramos assuming the presidency of Brazil until being peacefully succeeded by Juscelino Kubitschek a few months later.

The bloodless coup removed Carlos Luz from the presidency because he was suspected of plotting to prevent Kubitschek from taking office.

[5][6] The seeds of the coup began in August 1954 when associates of then-president Getúlio Vargas tried to assassinate opposition journalist Carlos Lacerda.

The Minister of War Euclides Zenóbio da Costa [pt], who had been part of the effort to remove Vargas, resigned and to replace him Café Filho appointed the relatively unknown and apolitical Henrique Teixeira Lott.

Unable to find a suitable candidate, General Juarez Távora, the primary author of the memorandum, eventually decided to run against Kubitschek while Café Filho promised to remain neutral.

Late on November 10, Lott met with other army leaders of the country including General Odylio Denys [pt].

They debated how to respond to Lott's removal as minister and decided that Denys would lead the army to seize key points in the country.

[2] By the morning of November 12, it became clear that forces friendly to Lott held the city of Santos and that they would not allow the Almirante Tamandaré to land.

He learned of the coup and considered resigning, but, after counterproductive conversations with Lott, he decided to wait to hear his doctors' evaluation on his health.

The supporters of Luz's brief presidency were never seriously punished although Mamede was briefly arrested and then later assigned to a remote army recruitment post.
